See, saving fish presents a fundamental PR problem, because we all know that fish are slimy monsters of the deep. Or are they? According to PETA they are "Sea Kittens!" A for effort on the cutesy-pushing, but nah.
Like their surface-dwelling cousins, the land kittens, sea kittens enjoy being petted. Their lack of arms makes it difficult for them to pet back, but they often gently rub against each other as a sign of affection.
Just tell people to read Peter Singer and STFU why don't you?
